The application of geophysical method in city active fault detection and its effect analysis

摘要

City active fault may cause serious harm for that habitable environmental for human being and buildings. We use the geophysics methods such as resistivity imaging, Ground penetrating Radar(GPR), transient eleciromagnetic(TEM) method and high resolution seismic reflection in the field work of active fault of Changchun city. In view of disadvantages such as many interfering factors and complex environments in city, using new methods and technology, data processing and explanation, and using the characteristics of different methods, we has obtained the ideal survey effect, practice proves that the synthetic geophysics method is a kind of effective and economic mean of active fault investigation in Changchun city.
